A question about step 12:
"12. das blacklist 870 error fix
purpose: avoid error 870 in das. use when needed only."

Why use only when needed, is there any harm to apply it always? Is there a list of blocked serial numbers to tell when this fix is needed?

I'm asking because I happened to test an old SDconnect clone with the serial 1010xx and 07.2019 XDOS and got the exclamation mark on the LCD! I was expecting the tool being bricked (waiting for the eeprom recovery) but looks like it did not get permanently blocked. Reboot the mux and try again with DAS fix and the mux seemed to be fine. Is this normal?
